The video signal transmitted from the video / audio digital transmission device (25) in the above-described scramble device is subjected to FM,
It is further converted to SHF band radio waves and transmitted to communication satellites.
The audio signal is digitally encoded by the PCM method, and the audio subcarrier is converted to a PSK (Phase Shift K
Eying) This is a PCA subcarrier system for modulation and transmission, and the actually transmitted signal is configured as shown in the frame configuration diagram of FIG. The audio signal is a digital signal in which one frame is composed of 2048 bits, and this signal is transmitted 1000 times per second. That is, as shown in FIG.
Data transmission of 2048 Mbits of 00 frames is performed. The frame synchronization in the A mode shown in FIG. 4B for this one frame configuration is for facilitating the reproduction of the bit clock on the receiving side with 16 bits. The next 16 bits of the frame synchronization are bits indicating the transmitting mode, and the receiver switches the receiving mode according to the receiving mode. The range bits are composed of 32 bits. These 32 bits are divided into four every 8 bits, and correspond to audio 1 to audio 4 of the audio signal. The first 3 bits of the 32 bits corresponding to audio 1 to audio 4 are range numbers. Range bits corresponding to
The remaining 4 bits are the error correction bits of the range bits, and the last bit is 0. In the B mode, there are no voices 3 and 4 as shown in FIG. 4C, so the 16 bits of the range bits are changed to bits for transmitting independent data (1). Audio 1 to audio 4 each have 320 bits, and audio 1 and audio 2 have 1536 bits in the B mode. The independent data is data that can be freely used by the user. Of the total of 480 bits (224 bits in B mode), 256 bits (16 bits in B bit) indicated by independent data (1) and 160 bits indicated in control data are already scrambled. It is used in a bra, and 64 bits × 1000 frames = 64 kBPS indicated by the independent data (2) can be freely used. The same is true for the B mode. The last 244 bits are added to voice and independent data by an error correction code. In this example, the independent data (2) of 64 kBPS for one second among the independent data is used, and a data format signal as shown in FIG. 5 is inserted into the independent data (2) and transmitted. In the figure, CH is channel information of each channel, such as a channel number, and the next program start and program end time information (9) is constantly transmitted for about two days. Of course, when the program is terminated, the information is not transmitted and a new program time is updated and transmitted. The next data (10) is correction standard time information for correcting a timer in a receiving device having a clock function. The transmitting device to which such information is constantly transmitted is always set to the receiving state on the contracted channel.

In the receiver having the above-described configuration, the channel information CH, program start / end time data (9) shown in FIG. time data is read (10) the first such step ST 1 of FIG. 2, the receiver (7)
For example, programs for about two days for each channel are displayed on the display section (7f) as shown in FIG. 1A. The contract user sees the contents of the 7-channel program from 8:00 to 10:00 on March 1, for example, in a newspaper or the like, determines whether or not to record, and presses the marker feed key (7j) when not recording. /1,8.00-1
The marker (7j) at the 0,0,7ch position is March 1 in the next column.
Move to 1ch program column from 10:00 to 12:00 a day. Here, if this program is viewed in a newspaper and the user does not want to record, pressing the cancel key (7c) cancels the program field. The same operation is performed for the program displayed on the display unit (7f). The cancel all recording key (7d) is used when simultaneously canceling all the programs displayed on the display unit (7f). Is the key. In this manner, only the program canceled in advance by the cancel key (7c) disappears from the nonvolatile memory (7g). Hereinafter, returning to the flowchart of FIG. 2 illustrating the operation of the present embodiment, the first step ST 1
When reading of channel information CH, program start and end time data (9), and standard time data (10) is completed
CPU (7e) is channel information CH been promoted to the second step ST 2, the program start end time data (9), writing updated standard time data (10) to the nonvolatile memory (7 g). This is done at each response time. Next third step
In ST 3 , the CPU (7e) compares the date and time generated by the calendar IC (7h) with the received standard time data (10).
If there is a time difference, a correction is made to match the received standard time data (10). The next fourth step ST 4 cancel key as described in the above (7c) and all cancel recording key (7
whether the operation of d) is performed, i.e. to determine whether cancellation of the program is present, there is a cancellation "YES" canceled proceeds to a fifth step ST 5, if the program start,
The end time data (9) and the channel information CH erased from the nonvolatile memory (7 g), the process proceeds to a sixth step ST 6. Even if there is no program cancel fourth step ST 4 proceeds to a sixth step ST 6. In the sixth step ST 6 CPU (7
e) retrieves the start and end times of the program from the non-volatile memory (7g). When sixth step ST 6 is completed, the timer in the timer function of CPU (7e) having seventh step ST 7, it is determined whether it is the start time of the predetermined search programs.
In the case of "YES" at the program start time, the power is turned "ON" to an external device such as a television receiver (11) or a VTR (8) by a control signal from the CPU (7e) and set to the corresponding channel. Then, start recording or start recording. Seventh
Step ST 7, it is determined whether it is the timer program end time, the ninth step ST 9 when the case and the eighth step ST 8 of "NO" is terminated, control from if "YES" CPU (7e) the power of the external device to "off" to stop recording the signal, the channel information CH eleventh step ST 11 in the finished program, program start and end time data (9) is deleted from the nonvolatile memory (7 g) Also when the ninth step ST 9 returned to the first step ST 1 is “NO”, the first step ST 1
Will be returned to.

Since the present invention is operated as described above, the operation for the program reservation on the receiving device side can select any reserved program only by pressing the cancel key. Although the present invention has been described for the case where a program is automatically recorded, it is apparent that the present invention can be applied to an answering machine and the like. Further, according to the transmitting apparatus of the present invention, the independent data of the skyport scrambler system can be effectively used, and the receiving apparatus can record the reserved program in accordance with the reference time. There is no possibility that the timer is out of order and the video is not leaked.
